Hey guys, so I'm given a long strand of protein (shown below). It is predicted to be nuclear localized but how can I know that it's nuclear localized just by looking at its primary sequence? I mean we can probably do some protein tagging to localize it experimentally but I have no idea how the prediction part comes about. Thanks in advance for any help.

does this have something to do with locating a part of the main sequence called the nuclear localization signal with indicates nuclear localization? and if so what is the sequence of the nuclear localization signal?
